instead of 1<<n. Speeds up things on SH1, and also reduces core binsize. Most notable speedups: 1 bit lcd driver: drawpixel +20%, drawline + 27%, hline +5%; jpeg viewer: +8% for 1/8 scaling. Other targets are unaffected.

struct plugin_api *rb is declared in PLUGIN_HEADER, and pointed to by
__header.api
the loader uses this pointer to initialize rb before calling entry_point
entry_point is no longer passed a pointer to the plugin API
all plugins, and pluginlib functions, are modified to refer to the
global rb
pluginlib functions which only served to copy the API pointer are
removed

three (for now - maybe it should be split further) files - jpeg.c (the main plugin/viewer parts), jpeg_decoder.c (the actual decoder) and. for colour targets only, yuv2rgb.c. The intention of this commit is as a first step towards abstracting this viewer into a reusable jpeg decoder and a multi-format image viewer.
